Problems solved by technology

[0002] There will be many holes through the wall during the construction, such as the bolt holes through the wall used for the tie between the inner and outer formwork of the wall formwork, the holes of the climbing frame on the outer wall, the holes through the wall for temporary scaffolding, and the air-conditioning holes, etc. For a large number of holes on the outer wall, if not handled properly, it is very easy to cause quality problems after the project is put into use
It is not uncommon to see engineering quality problems of external wall leakage due to insufficient sealing of the through-wall holes, which has brought great troubles to the owners, and disputes caused by this have...

Embodiment 1

[0039]

[0040]

[0041] Preparation method: Weigh various raw materials according to the formula, add aggregate (graded quartz sand), powder filler (calcium carbonate powder), cement (P.O42.5 ordinary Portland cement), active blending Material (slag fine powder), water reducer (naphthalene series high-efficiency water reducer), early strength agent (anhydrous sodium sulfate), expansion agent (UEA expansion agent), binder (ethylene / vinyl acetate latex powder), hydrophobic Water agent (silicone powder), plasticizer (methyl cellulose) starch ether, fully stirred evenly, and packaged to form a product.

[0042] The construction method is as follows:

[0043] ①Clean and moisten the hole through the wall before the sealing construction, and blow off the floating water with compressed air.

[0044] ② Add water to the cement-based sealing material according to the ratio requirements, the amount of water added is 17% of the dry powder weight of the sealing mortar, and use a han...

Embodiment 2

[0052]

[0053]

[0054] Preparation method: Weigh various raw materials according to the formula, add aggregate (graded quartz sand, expanded perlite), cement (sulfoaluminate cement 42.5 grade), active admixture (silica fume), Water reducer (melamine high-efficiency water reducer), early strength agent (sodium silicate), expansion agent (calcium oxide), water repellent (organic silicon powder), plastic retainer (bentonite, hydroxyethyl cellulose ether), Modified starch ether, fully stirred evenly, packaged to form a dry powder product. The binding agent is weighed by comparison, and packaged to form a liquid product.

[0055] The construction method is as follows:

[0056] ①Clean and moisten the hole through the wall before the sealing construction, and blow off the floating water with compressed air.

[0057]②According to the ratio requirements, weigh the sealing material dry powder and liquid product in proportion, take water according to 20% of the weight of the dr...

Abstract

The invention relates to cement-based shrinkage-free wall hole-penetrating blocking materials and a preparation method and a construction method. The materials comprise, by weight, 100 cement, 0-100 active admixture, 0.01-10 water reducing agent, 0.01-10 early strength agent, 0.1-30 expanding agent, 0-20 adhesion agent, 0-10 water repellent, 0.01-30 plastic retaining agent, 0.01-10 starch ether, 0-60 power filler and 0-300 aggregate. Compared with the prior art, the cement-based shrinkage-free wall hole-penetrating blocking materials have the advantages of being good in construction performance, and long in operational time. New mixing slurry has good plasticity, adhesive power and anti-falling performance, a caulking gun or a caulking machine can be used for pressing, injecting or sealing holes, a flowing phenomenon cannot appear even big holes are filled, and the big holes can be filled until the big holes are full and until reaching the deep hole, and completely sealed, and the sealing materials can fully come into play.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and in particular relates to a novel plugging material for building through-wall holes, a preparation method and a construction method thereof. Background technique [0002] There will be many holes through the wall during the construction, such as the bolt holes through the wall used for the tie between the inner and outer formwork of the wall formwork, the holes of the climbing frame on the outer wall, the holes through the wall for temporary scaffolding, and the air-conditioning holes, etc. For a large number of holes on the outer wall, if not handled properly, it is very easy to cause quality problems after the project is put into use. It is not uncommon to see engineering quality problems of external wall leakage due to the incomplete sealing of the through-wall holes, which brings great troubles to the owners, and disputes caused by this occur from time ...
